Wall We present a method to recover the reflectance of objects and the parameters of multiple lights using a 3D image acquired by a depth sensor and a stereo intensity pair. Experimental evaluation shows the ability to recover varying diffuse and constant specular reflectance parameters from object images, and simultaneously the locations and intensities of up to three distinct light sources. 2008 Elsevier B.V.
